I have now sold my 2005 V-Strom and removed the rather nice Nitron NTR-R1 Shock.
http://www.Nitron.co.uk/catalogue_item.phpAccording to the Nitron website it will fit 2004 - 2011 models, it is adjustable for rebound damping and ride height and it also has the optional Remote Pre-Load Adjuster. New price is £648.
It has been on my bike for a few years, but only done about 5,000 miles, I got it as I had lent Nitron a couple of bikes for dev work (including my strom) so they did me a deal I could not refuse and fitted it whilst they borrowed my Strom.
It is in very good condition and a huge improvement over the standard unit, it is fully serviceable and Nitron charge £65.00 for a service or £95.00 for a full rebuild. (exc. VAT)
I am looking for £300 plus postage (£25) or pickup from Witney area.
PM me if you want more details or pictures.
